Application October 1,

7 Claims.

This invention relates to an improvement in spindle swings for spinningmachines.

The object of my invention is to improve the manner of lubricating thestem of the swing, so as to keep said stern lubricated and to protect itfrom dust and humidified air of the silk mill which thereby preventsrusting 0r corroding of the bearing.

This object is accomplished. by applying the lubricating oil through anopening in the end of the stem where it may flow down into theperipheral groove thereof and protecting said opening by means of aspring-pressed ball or the like, which will keep it normally closed tothereby exclude dust and humidifying air from gaining access to theperiphery of the stem and the bearing thereof in the well. A washer offelt or other absorbent material is placed between the well and theswivel to protect the bearing from dust and humidified air andconsequently prevent rusting or corroding thereof. This washer alsoprevents dirt or lint from lodging in the joint as well as preventingthe oil from working up the stem and splashing over outside of thespring. I provide a ball thrust bearing in the bottom of the well to beengaged by the lower end of the stem in order to give point contacttherewith, and to allow positive free movement of the stem.

In the accompanying drawing,

Fig. 1 is a partial sectional view through my improved spindle swing;

Fig. 2 is a horizontal sectional view therethrough on the line, 2-2, ofFig. 1; and

Fig. 3 is a top plan view thereof.

I refer to the patent to Bradley, No. 1,616,949, February 8, 1927, asillustrating the general form and arrangement of spindle swings thathave been used heretofore; that illustrates the manner of use of theswing and since it is well-known in the art, I have not shown my swingapplied to the rail of a spinning machine since it would be used in thegeneral manner disclosed in the Bradley Patent referred to.

Referring to the drawing, the well 1 is of the usual construction and isprovided with a threaded lower end 2, adapted to be screwed into thespindle rail of the spinning machine, and this well is provided with aninternal recess 3, forming a bearing therein which extends downwardlyfrom its upper end.

The spindle supporting arm is designated 4 and is of the usualconstruction for supporting the spindle in the outer free end thereof,the inner end being provided with a hub 5 in which is rigidly fixed astem 6 having a peripheral spiral 1932, Serial No. 635,803

lubricating groove 7 therearound from the lower to the upper endsthereof. The stem 6 has a turning fit in the bearing 3 of the well andthe lower end of the stem rests on a ball thrust bearing 8 placedloosely within the bottom of the bearing 3, so as to give point contactfor the lower end of the stem and very free movement thereof in itsbearing. 3

The upper end portion of the stem has an oil hole 9 extending downwardlytherein communicating at its lower end with a lateral passage 10 whichleads from the oil hole 9 into a portion of the peripheral groove '7, soas to supply lubricating oil thereto. This enables the oil for thebearing of the stem to be applied through the stem, so as to insure thatall of the oil reaches the bearing without any of it splashing over onthe outside of the well or the spring. The upper end of the stem 6 iscounterbored as at 11 to receive a housing 12 having an orifice 13throughthe upper end thereof and through which the oilis inserted forlubricating the bearing of the stem.

A ball check valve 14 is provided for normally closing this orifice 13,said check valve being supported by a spring 15 which acts thereon andbeing interposed between the check valve and the lower end of thehousing 12. This check valve allows the bearing to be oiled through theupper end of the stem, but it keeps the oil hole normally closed toprevent dirt, lint, or moisture from passing into the bearing throughthe oil hole.

Interposed between the hub 5 and the upper end of the well 1, is awasher 16 of felt or other absorbent material which protects the bearingfrom the humidified air of the silk mill and consequently preventsrusting or corroding of the bearing. This Washer also prevents dirt orlint from lodging at this joint, as well as preventing the oil fromworking up the stem and splashing over outside the well.

The usual spring is designated 17 and has one end secured to a rib 18 onthe side of the well, while its other end is secured to a rib 19 on theinner side of the arm 4. This spring acts to normally hold the whirl ofthe wind-up spool carrying the spindle in driving contact with a belt.

From the foregoing description, it will be seen that I have materiallyimproved the spindle swing particularly in the manner in which the stemis lubricated and the lubrication protected and the provision of a ballthrust valve for the lower end of the stem which effects free movementthereof, which results have been demonstrated by the actual use of theseswings In View of the improved results, the trade has recognized thesuperiority of my swing and it is already replacing others that havebeen used heretofore.

My improvements may be used either in the manufacture of new swings ormay be applied to the old type of swings which may be reconditioned withthese improved features at comparatively small cost.

I claim:

1. A spindle swing comprising a well, an arm, a stem connected with thearm and extending into the well, said stem having an oil hole extendingthrough the upper end thereof and having lateral communication with aside of the stem within the well, a housing enclosed within the upperend portion of the oil hole, a valve in the housing in position to beseated therein, and a spring normally tending to hold the valve seatedfor closing the oil hole.

2. A spindle swing comprising a well, an arm having a hub, a sternsecured to the hub and extending into the upper end of the well, saidstem having an oil hole through the upper end thereof communicating withits periphery, and a washer of absorbent material interposed between thehub and the end portion of the well and closing the space therebetweenin position to prevent splashing over of lubricant. from within the wellonto the outside thereof.

3. A spindle swing comprising a well, an arm, a spring. coiled about thewell and having opposite ends connected with the well and arm, a stemconnected with the arm and extending into the.- well, said stem having aspiral lubricating groove in the periphery thereof extending to a 'pointabove the well, and having an oil hole through the upper end thereofcommunicating with said groove, and an absorbent washer interposedbetween the upper end of the well and the arm in position to preventsplashing over of lubricant from the groove onto the, spring and toprotect the bearing from dust and humidified air.

4. A spindle swing comprising a well, an arm, a stem secured to the armand extending into the upper end of the well, said stern having aperipheral lubricating groove extending along the length thereof, awasher of absorbent material interposed between the arm and the upperend of the well and closing the space therebetween in position toprevent splashing over of lubricant from the groove onto the outside ofthe well and to protect the bearing from dust and humidified air, and aball freely disposed in the bottom of the well and supporting the lowerend of the stem by direct contact therewith.

5. A spindle swing comprising a well, an arm, a stem connected with thearm and extending into the well, said stern having an oil hole throughthe upper end thereof communicating with the periphery of the stem, andan absorbent washer surrounding the stem between the upper end of thewell and the arm in position to exclude dust and humidified air from thewell.

6. A spindle swing comprising a well, an arm, a stem connected with thearm and extending into the well, said stem having an oil holeapproximately through. the center thereof with lateral communicationwith the periphery of the stem at a point within the well, and anabsorbent 100 washer fitting around the stem at the top of the well andbeneath the arm, in position to exclude dust and humidified air fromwithin the well andprevent splashing of lubricant.

'7. A spindle swing comprising a Well, an arm, 105 a stern connectedwith the arm and extending into the well, said stem having a spirallubricating groove in the periphery thereof extending to a pointapproximately at the upper edge of the well, said stem having an oilhole approximately '10 through the center thereof with lateral communication with the spiral groove at a point within the well, and anabsorbent washer fitting around the stem at the top of the well andbeneath the arm for protecting the well and confining lubri- 5 canttherein.
